There are mainly several aspects:
1. Detection distance: 1.1~1.5 meters for acousto-magnetic labels, 0.7-0.9 meters for electromagnetic wave magnetic strips, because acousto-magnetic labels are more suitable for open stores with more traffic than electromagnetic wave magnetic strips in terms of detection distance.
2. Reusable: Acoustic magnetic labels are not reusable, and electromagnetic wave magnetic strips are divided into reusable and permanent.
3. Material: The shell material of the acousto-magnetic label is polystyrene, and the electromagnetic wave is divided into cobalt-based and iron-based (the first one is not rusted and the other is easy to rust in wet areas)
4. Frequency: The acousto-magnetic label has a fixed frequency of 58KHz, and the principle of the magnetic strip is mainly to cut the magnetic field lines, and there is no frequency.
